I just noticed that my new rigol DS1052E oscilloscope doesn't have the Ultra-zoom logo on the top sticker, I'm pretty confident that its not a counterfeit, it looks exactly like the ones online and Dave's except for that. Its firmware looks exactly like Dave's and it came in a Rigol stamped box, with Rigol packaging tape unopened. It also has the certificate of calibration, Rigol software CD etc. the internals have the same shielding visible, but I'd rather not open it.
Is it just an older model ? (FW 2.02) or just from Rigolna (China) instead of Rigol (USA).
Everything seems to work fine, what does the Ultra-zoom do exactly, how would I know if i had it or not ?
